Abstract
A calibrated magnetic random access memory (MRAM) current sense amplifier includes a first plurality of trim transistors selectively configured in parallel with a first load device, the first load device associated with a data side of the sense amplifier. A second plurality of trim transistors is selectively configured in parallel with a second load device, the second load device associated with a reference side of the sense amplifier. The first and said second plurality of trim transistors are individually activated so as to compensate for device mismatch with respect to the data and reference sides of the sense amplifier.
